And even if a customer is "caught" trying to do a return scam, nothing will be done. My wife's best friend recently quit a job in the security dept of a large chain store. She and a co-worker stopped two teenaged girls who had openly put on a couple of very expensive leather jackets and walked out with them. They were ordered to let the girls go and not to try to detain anyone doing the same in the future. Not a return scam, but same mentality. Supervisor told the employees they just needed to be around and be obvious to attempt to worry thieves enough maybe they would not steal. Pointless. The friend gave her notice that day and quit. By the way, they had the girls cold on the store's security videos.
